How much fluid does a 2018 f350 differential hold?
As a seasoned auto service provider, I often encounter questions about vehicle maintenance, particularly regarding fluid capacities. One common inquiry is about the differential fluid capacity of the 2018 Ford F-350. Understanding this aspect is crucial for maintaining your vehicle's performance and longevity.
What is a Differential?
The differential is a vital component of your vehicle's drivetrain. It allows the wheels to rotate at different speeds, especially when turning, which enhances handling and stability. Proper maintenance of the differential, including regular fluid changes, is essential to ensure its smooth operation.
Differential Fluid Capacity for the 2018 F-350
The 2018 Ford F-350 comes with different differential options, and the fluid capacity can vary based on the specific configuration. Here are the general capacities:
- Single Rear Wheel (SRW) with 3.31 or 3.55 Axle Ratio: Approximately 3.5 quarts of fluid.
- Dually (DRW) with 3.31 or 3.55 Axle Ratio: Approximately 4.5 quarts of fluid.
- Single Rear Wheel with 3.73 or 4.10 Axle Ratio: Approximately 3.5 quarts of fluid.
- Dually with 3.73 or 4.10 Axle Ratio: Approximately 4.5 quarts of fluid.
It's important to check your owner's manual for the exact specifications related to your specific model and axle configuration, as these can influence the required fluid amount.
Why is Differential Fluid Important?
Maintaining the correct level and quality of differential fluid is crucial for several reasons:
- Lubrication: The fluid lubricates the gears and bearings within the differential, reducing friction and wear.
- Heat Dissipation: It helps dissipate heat generated during operation, preventing overheating and potential damage.
- Contaminant Removal: Differential fluid also helps to remove contaminants and debris that can accumulate over time.

Frequently Asked Questions
How much front differential fluid do I need?
For most cars, the differential may hold around 1 to 2 quarts of oil. Heavy-duty trucks or commercial vehicles may require more.
How much oil does a F350 rear differential take?
The correct fluid level is achieved when a stream of fluid begins overflowing from the differential fluid fill port. The fill capacity for the Ford F-350 Dana 80 rear differential is 4.0 liters or 4.25 quarts.
How much oil does a 2018 6.7 powerstroke take?
The 6.7 Powerstroke's oil capacity is 15 quarts if your Ford F-250 to F-600 was produced after 2022. Those from 2011 to 2022 should hold approximately 13 quarts.
How many quarts are in a rear diff?
1 quart for the replacement. But if you plan on squeezing the quart bottle to refill diff after draining, purchase 2 quarts. Getting that last 3 or 4 ozs out of the bottle is tough, because of the tight location and elevation of the bottle itself in relation to the diff.
How much fluid does a 6.7 Powerstroke front differential hold?
Front differential: 3 quarts for the 2011-2016 models and 2.7-2.75 quarts for 2017-2020. Rear differential: 3.5-7 quarts for the 2011-2016 models and 3.1-3.78 quarts for 2017-2020. Diesel exhaust fluid (DEF): 5-6 gallons for the 2011-2016 models and 7.2-7.4 gallons for 2017-2020.
How many quarts does a 2018 6.7 powerstroke take?
The 6.7 Powerstroke's oil capacity is 15 quarts if your Ford F-250 to F-600 was produced after 2022. Those from 2011 to 2022 should hold approximately 13 quarts.
How much fluid goes in the rear differential?
towing capacity using a rear differential that holds between 3.3 and 3.5 quarts of fluid. This means less lubrication is responsible for protecting gears against increased heat and stress.
How much gear oil does a 2018 f250 take?
3.5-3.6 quarts
Manufacturer recommends the use of Motorcraft Premium Hypoid Gear lubricant, P/N XY-75W85-QL (WSS-M2C942-A). Capacity: 10.5 RG With O locker Rear 7.2 pints. Capacity varies from 3.5-3.6 quarts (3.3-3.4 Liters).
What happens if you never change differential fluid?
Most differentials need a fluid change at about 50,000 miles. If left too long or if the fluid starts to run low, the differential will become noisy and can eventually fail. If that happens, the gears can seize, locking up the rear wheels and potentially causing a lot of damage or even an accident.
